FPGA Implementation Of QAM
Field programmable gate array (FPGA) implementation of Quadrature Amplitude Modulation (QAM) is
presented. The system implements 8 point QAM. The system is suitable for realization of the digital baseband-modulation
part of software-defined radio systems. In addition, this kind of implementation can be used for educational purposes.
Quadrature Amplitude Modulation (QAM) is widely used due to its spectrum efficiency. The proposed system accepts input
message signal from the external user. Xilinx ISE 14.6 for the Verilog code simulation and hardware implementation is done
on Spartan 3 XC3S400 FPGA board using Xilinx ISE 14.6 and iMPACT (manage configuration project process) software.
The real time output is viewed on a digital storage oscilloscope.
